Our results using conventional transmission electron microscopy has shown that ER is changed during the various mammary gland development stages. We found that the average relative volume of ER achieves 17.7±2.464% of cytoplasm volume in the stage of lactation. During regression ER relative volume decreased to 1.274% of the cytoplasm. This difference compared to lactation is statistically significant (p
